Re: DSK Woes and other stories

["Frank Townsend" <ftownsen@iamdigex.net>]

I have the last free complete version available from the Apple FTP site
(7.5.3, I think).

I have a feeling that the only reason the files aren't forked is because I'm
FTP'ing them as binary files.  I use the NCSA free Telnet client which
includes an FTP server.  I set the preferences to Binary filetype BINA.
Dunno, really, but it works.

Thanks for the suggestion.

I'll try it again.

I now have the newest version of DSK2FILE ver. 5.7 from  Ron Kneusel.  It is
Freeware (by which he means copyrighted free software) and is really nice.
It allows you to toggle DOS 3.3 and ProDOS sector ordering as well as other
things which were harder to do in the older version.
